Claims.

This invention isdirected to an adjustable telephone support and particularly tol a` telephone supporting means adapted tol be used Vinpubllic telephone booths and capable o f easy adjustment 5 bly authorized workmen, but notbly the users, into positions designed fora standing or a seateduser, asdesired.

Since my improved telephone suppolrtfis particularly adapted for use in a telephonefbooth it will be soldescribed, altholughits use obviously is nolt so limited. My improved telephone support may beused to advantage in lany telephone booth, blut is specifically designedfolr use inv a telephone booth of the type described land claimed in my copending application, Serial Nol. 120,322, led

January 13, 1937, and sol will be specicallyldescribed with reference thereto.v .I

In the accompanying drawings: l

, Fig, 1 is a vertical section through a telephone booth of the type described in my saidaplplication, showing my telephone support in place and positioned for use bya seated person.

Fig. 2 is a detail View of the telephone shelf and supporting panel. T Fig. 3 is a vertical section on the linel 3- v-3` in Fig. 2. l f Fig, 4 is a sectional view similar to Fig., 3 but showing the support adjusted for useby astandfingperson. l ',r n .f- Fig. 5 is a detail view olf the bell box supporting plate. l l Fig. 6 isa fragmentary'dtail View of the telephone shelf; and l Fig. 7 is a detail view of the lower end olf the supporting panel.

The telephone booth sholwn in Figure 1 comprises essentially an outer wall I, an inner wall 3 spaced therefrom land extending around three sides of the booth, sound insulation 5 between the walls, a floor assembly I welded to theouter wall I, a hinged, removable roof 9 and a ceiling II spaced from the roof.

Positioned within the booth is a seat assembly I3 secured in bracket I5 which is fastened to the floor assembly 'I by machine screws I'I and thus may be easily removed by removal of the screws.

A hollow cylindrical standard I9 extends from door to ceiling withinlthe booth adjacent the rear corner thereof opposite the seat I3, and opens into the space 2| above the ceiling through aperture 23 vin the ceiling I I.`

A strap 25 is welded or otherwise secured to standard I9 at a point somewhat more than half way from the iioor to the ceiling, and in this strap facing the booth interior, are provided four tapped holes tolreceive machine screws 29.

A blackboard 3l is mounted slidably on standard I9 by means of straps 33, 33 xedly secured thereto and slidablle on standard I9,l Eight holes 5 3'! large enough to receive screws. 29 are drilled in the body of blackboard 3l and are arranged in two groups of four each, each group of four being arranged in thel same relative position as the holes y in strap 25. The holes 3l are so arranged that "10 when the blackboard 3i is in lower position with strap 33 contacting the fixed strap 25, as shown in Fig. 3, the holes in strap 25 will coincide with the upper group of holes 3l and screws 29 may be passed through blackboard 3l and ntlol strap 25 `15 to secure the former firmly to standard I9.` Simil'larly, when the backboard 3l is in upper position 4metal land is provided with a flange il at the rear for attachment to the blackboard and a skirt 43 3o alonglthelfront and side edges. Thefree rear edges of the shelf closely abut the inner wall 3 of the booth, as shown in Fig. 1, The shelf 39 is` centrally stiffened and reinforced by a plate 45 positioned beneath the central portion thereof, and 35 having a depending flange 4l of varying width secured tol flange 4I and skirt 43 o'f the shelf.

An aperture 48 in the top and rear flange olf plate 54 is aligned with an aperture l2 in the flange 4I olf shelf 39, and both apertures are 40 aligned, when the structure is assembled, with the lower end oli slolt 32, as shown in Fig. 3.

The telephone instrumentalities may be secured to the backboard 3l or may be positioned on the shelf 39, or partly in one way and partly in the 4,5 other. The bell box may conveniently be secured in place on the under side of plate 45, as shown in Fig. 3.

The wires for the telephone instruments will colnveniently be brought into the booth from the 50 top, along the channel 159 adjacent the edge of roolf 9, through one olf the apertures 5I into the space 2| and thence into the interior of hollow standard I9 through aperture 23. From the interior of standard I9 the wire, shown as 53, will 55 pass, when the backboard 3| is in its lower position, through aperture in the standard I9, and slot 32 in the backboard 3I to the telephone instruments on the backboard or shelf 39; and down `the slot 32 and through apertures 42 and 48 tothe bell-box 65. When the backboard 3I is in its upper position the wire 53 will enter slot 32 centrally and may pass up the slot to the telephone instruments, and down the slot to the bell box, as shown in Fig. 4.

It will be appreciated that the telephone booth may be readily converted for use when standing by removing seat assembly I3 and bracket I5., taking out the four screws 29, sliding the backboard 3I and shelf upwardly on standard I9 until plate 33' contacts strap 25 and replacing screws 29. The wiring arrangements need not be disturbed, since any necessary increase or decrease in the length of wire used will be compensated by using or replacing slack wire left for the purpose in the interior of standard I9.

If it is desired to conceal the wires lying in slot 32 a removable cover plate having an opening for wires at the top may be provided to cover the eX- posed portion of the slot.

By reason of the fact that screws 29 cannot be removed except by the use of a suitable tool, the position of the backboard cannot easily be changed by the transient user thereof. This is desirable, since possible injury to the equipment is thereby averted.

This application is led as, and constitutes, a continuation-in-part of my copending application Serial No. 122,363, led January 26, 1937.
